I just got another e-mail with a reduced rate to join the Academy. But, my earlier e-mail to them went unanswered, so am hesitant to join.
The John Armstrong VHS was never made on DVD, at least not that I could find. It must have been made pre-DVD days. Its a real shame, because John Armstrong was truly a titan in O-scale (in the league of Frank Ellison); and, out of hundreds of layout videos I've seen over the years, his layout and the interview stands out as the best ever. I recall him saying he had about 50-years of work in his layout. John passed away in 2004.
